RUGGEDCOM RX1501Installation GuideChapter 2Installing the DeviceCabling Recommendations 15Communication PortsConnect to any of the available Ethernet ports on the device to access the ROX II console and Web interfaces viathe device's IP address. For more information about available ports, refer to Chapter 3, Communication Ports.Section 2.6Cabling RecommendationsSiemens recommends using SIMATIC NET industrial Ethernet shielded cables for all Ethernet ports.Refer to the following sections for further recommendations and considerations:• Section 2.6.1, “Protection On Twisted-Pair Data Ports”• Section 2.6.2, “Gigabit Ethernet 1000Base-TX Cabling Recommendations”Section 2.6.1Protection On Twisted-Pair Data PortsSiemens does not recommend the use of copper cabling of any length for critical, real-time substation automationapplications. All copper Ethernet ports on RUGGEDCOM products include transient suppression circuitryto protect against damage from electrical transients and conform with IEC 61850-3 and IEEE 1613 Class 1standards. This means that during a transient electrical event, communications errors or interruptions may occur,but recovery is automatic.Siemens also does not recommend using copper Ethernet ports to interface with devices in the field acrossdistances that could produce high levels of ground potential rise (i.e. greater than 2500 V), during line-to-groundfault conditions.Section 2.6.2Gigabit Ethernet 1000Base-TX Cabling RecommendationsThe IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbit/s Ethernet communications over distances of upto 100 m (328 ft) using all 4 pairs in category 5 (or higher) balanced, unshielded twisted-pair cabling. For wiringguidelines, system designers and integrators should refer to the Telecommunications Industry Association (TIA)TIA/EIA-568-A wiring standard that characterizes minimum cabling performance specifications required for properGigabit Ethernet operation. For reliable, error-free data communication, new and pre-existing communicationpaths should be verified for TIA/EIA-568-A compliance.The following table summarizes the relevant cabling standards:Cabling Category 1000Base-TX Compliant Required Action< 5 No New wiring infrastructure required.5 Yes Verify TIA/EIA-568-A compliance.5e Yes No action required. New installations should be designed with Category 5e or higher.6 Yes No action required.> 6 Yes Connector and wiring standards to be determined.
